# J-PoleScad #

Openscad script to draw a ladderline J-Pole antenna with dimensions once given a center frequency.

## References

The libraries for drawing the dimension lines where downloaded from:

* [dimlines.scad](https://github.com/pwpearson/dimensional-drawings/tree/master)
* [TextGenerator.scad](https://www.thingiverse.com/thing:59817)

They where both modified in order to work with the newest version of OpenScad at that time.
